참당귀와 일당귀의 부위별 휘발성 정유성분 비교

Abstract

Volatile flavor compounds Angelica gigas Nakai and Angelica acutiloba Kitagawa were extracted by SDE (simultaneous steam distillation extraction) using the mixture of n-pentane and diethylether (1:1, v/v) as an extract solvent and analyxed by GC-FID and GC-MS. The amount of exxential oils of top part and root in Angelica gigas were obtained in 0.063% (v/w) and 0.389% (v/w) yields as a fresh weight base, respectively. The main compounds in top parts and the root were identified as nonane (7.51% and 24.49%, respectively), α-pinene (14.64% and 31.75%), limonene+β-phellandrene (14.01% and 9.66%), γ-terpinene (7.85% and 1.20%),germacrene-d (5.85% and 0.22%), (E,E)-α-farnesene (6.05% and 1.40%), β-eudesmol(5.26% and 1.84%). Although these compounds were present in both parts. The results showed large differences in the concentrations of them much varied. The amount ofexxential oils stem and leaf obtained(0.068% and 0.127% in A. gigas) and (0.153% and 0.243% in A. acutiloba) yields as a fresh weight base, respectively. More than 18 and 32 components in stem and leaf have been dientified, which of main components in A. gigas were α-pinene, myrcene, limonene, germacrene-d eudesmol and butylphthalide, but germacrene-d and butylphthalide conteents were also ddifferent in stem and leaf. And more than 21 and 32 components in A. acutiloba were γ-terpinene and bytylphthalide. Volatile compounds were very different in both species.
